Introduction
Imagine a world where one species suddenly disappears, forests are destroyed, or pollution fills rivers and oceans. What would happen to the other organisms living in that ecosystem?
An ecosystem is like a web in which living organisms and their environment depend on one another. Even a small change can affect the balance of the entire ecosystem.
In this WebQuest, you will become an Ecosystem Investigator. You will explore how organisms interact with one another and discover how human activities can affect ecosystem balance. You will then use what you have learned to propose ways of protecting and restoring ecosystems.
Task
Your task is to investigate an ecosystem and determine how different organisms and environmental factors are connected.
Working individually or in small groups, you will:
Choose an ecosystem such as a forest, marine ecosystem, freshwater ecosystem, or grassland.
Identify its major biotic and abiotic components.
Explain the relationships among organisms using a food chain or food web.
Investigate at least one human activity that threatens the ecosystem.
Explain how this activity affects the balance of the ecosystem.
Propose practical solutions to help protect or restore the ecosystem.
Final Product
Create a digital ecosystem presentation or infographic containing:
Name and description of the ecosystem
Biotic and abiotic components
Food chain or food web
Human activity affecting the ecosystem
Effects of the disturbance
Proposed solutions
A short reflection on why ecosystem balance is important
Process
Process
Step 1 – Choose an Ecosystem
Choose one ecosystem to investigate:
Forest
Marine ecosystem
Freshwater ecosystem
Grassland
Mangrove ecosystem
Step 2 – Investigate the Ecosystem
Research your chosen ecosystem and identify:
Producers
Consumers
Decomposers
Abiotic factors such as sunlight, water, temperature, soil, and air
Record important information from reliable sources.
Step 3 – Create a Food Web
Identify several organisms in your ecosystem and determine how they depend on one another.
Create a food chain or food web showing the flow of energy from producers to consumers.
For example:
Sun → Grass → Grasshopper → Frog → Snake → Eagle
Step 4 – Identify an Environmental Problem
Choose one human activity that may disturb your ecosystem, such as:
Deforestation
Pollution
Overfishing
Illegal hunting
Mining
Climate change
Plastic waste
Explain what happens to the ecosystem because of this activity.
Step 5 – Analyze the Effects
Answer these questions:
Which organisms are directly affected?
Which organisms may be indirectly affected?
How does the disturbance affect the food web?
What could happen if the problem continues?
Step 6 – Develop Solutions
Suggest at least three realistic actions that individuals, communities, or governments can take to protect the ecosystem.
Explain how each solution can help restore or maintain ecosystem balance.
Step 7 – Create Your Final Product
Present your findings through a digital presentation or infographic.
Make sure your work is:
Accurate
Organized
Creative
Easy to understand
Supported by reliable sources
Include a list of references at the end.
Evaluation
Evaluation
Your WebQuest output will be evaluated based on the following criteria:
1. Content Accuracy – 4 points

2. Ecosystem Analysis – 4 points
Clearly explains the relationships among organisms and the effects of environmental disturbances.
3. Food Web – 4 points
The food chain or food web is accurate, complete, and clearly shows the flow of energy.
4. Proposed Solutions – 4 points
Provides realistic, practical, and well-explained solutions to protect or restore the ecosystem.
5. Creativity and Organization – 4 points
The presentation is creative, well-organized, visually appealing, and easy to understand.
6. Sources and References – 4 points
Uses reliable sources and properly acknowledges or lists the references used.
Total: 24 points
Grading Scale
21–24 points – Excellent: Demonstrates a strong understanding of ecosystem balance and provides a complete, accurate, and creative output.
17–20 points – Good: Demonstrates a good understanding of the topic with only minor areas for improvement.
13–16 points – Satisfactory: Demonstrates a basic understanding but some information or explanations need improvement.
12 points and below – Needs Improvement: Demonstrates limited understanding and requires further research and revision.
Conclusion
Conclusion
Congratulations, Ecosystem Investigators!
Through this WebQuest, you have learned how living organisms and non-living factors interact within an ecosystem. You have also explored how human activities can disturb these relationships and affect the balance of nature.
Every organism plays an important role in maintaining a healthy ecosystem. By understanding these relationships and taking responsible actions, we can help protect biodiversity and our environment for future generations.
Reflection
After completing the WebQuest, reflect on the following question:
What is one action you can take in your daily life to help protect the environment and maintain ecosystem balance?
Write a short reflection explaining your answer and what you learned from this activity.

Overview
This WebQuest is designed to help learners understand the relationships among organisms and their environment. Through online research and inquiry-based activities, learners will investigate an ecosystem, identify its biotic and abiotic components, construct a food chain or food web, analyze human activities that threaten ecosystem balance, and propose possible solutions.
The activity encourages learners to develop research, critical-thinking, collaboration, communication, and environmental-awareness skills.
Learning Objectives
At the end of the WebQuest, learners should be able to:
1. Identify the biotic and abiotic components of an ecosystem.
2. Explain the relationships among organisms within an ecosystem.
3. Construct a food chain or food web showing the flow of energy.
4. Describe how human activities can affect ecosystem balance.
5. Analyze the possible effects of environmental disturbances.
6. Propose practical solutions for protecting and maintaining ecosystems.
7. Demonstrate responsible use of online information and resources.
Learning Standards
This WebQuest supports learners in developing their understanding of ecosystems, biodiversity, energy flow, organism interactions, and environmental conservation.
It also promotes the development of 21st-century skills, particularly:
- Critical thinking
- Research and information literacy
- Communication
- Creativity
- Collaboration
- Problem-solving
Teacher's Instructions
Before the activity, introduce the concept of ecosystems and briefly discuss biotic and abiotic factors, food chains, food webs, and ecological balance.
Divide the learners into small groups or allow them to work individually.
Guide the learners through the WebQuest by asking them to follow the Introduction, Task, Process, Resources, and Evaluation sections in order.
Remind learners to use reliable sources and properly acknowledge the information and images they use.
During the activity, monitor the learners' progress and provide guidance when necessary.
At the end of the activity, allow learners to present their digital presentation or infographic and discuss their findings with the class.
Assessment
Learners will be assessed based on:
- Accuracy and completeness of information
